Want a prepaid iPhone? Setup an iPhone for a pay-as-you-go plan

Aug 1, 2010 - 271 Comments

prepaid iphone You can use any iPhone, iPhone 3G, or iPhone 3GS as a pay-as-you-go phone through AT&T’s GoPhone program. AT&T doesn’t officially support using GoPhone with iPhone but that doesn’t mean you can’t do it, and it’s actually much easier than you might expect. You will be able to make calls and use prepaid data, and the best part about this… it does NOT require a Jailbreak!

Setup iPhone as a prepaid phone

Setting up an iPhone as a prepaid phone is actually very easy. First you will need a compatible phone, the original iPhone, iPhone 3G, and iPhone 3GS all work fine. Then all you need to do is:

  • Get a prepaid GoPhone sim card
  • Replace the iPhone sim card with the prepaid sim card

Yes, it’s that easy.

The best way to do this is to buy a really cheap GoPhone, which is usually a refurbished older Nokia or Samsung cell phone for about $25, and then yank out the sim card and swap it into the iPhone. Once you have the new GoPhone sim in the iPhone you can use it as you would with any other prepaid phone and make all the calls you want.

At this point you can make all the calls you want using the pay as you go model, but you are unable to use any data unless your iPhone is connected to WiFi. This is fine for some people, but in case it’s not there’s a workaround…

Setup iPhone to use a prepaid data plan

So your iPhone now makes calls fine but you want to use wireless data as well… no problem. Here are the steps:

  • Be sure you are on a WiFi connection so you can access the web on your iPhone
  • Using Safari on the newly setup prepaid iPhone, visit unlockit.co.nz and tap ‘Continue’
  • On the next screen tap on ‘Custom APN’
  • Select the carrier, for this example it’s going to be “US – AT&T” since using AT&T doesn’t require a jailbreak or unlock
  • Tap on the “Create Profile” button to create and download the custom APN profile
  • You will then see a screen saying you are about to install a new profile, click on ‘Install’ and then “Replace”
  • A “Profile Installed” screen will appear next showing the new APN profile that has been installed
  • The data plan should now work

To test that the prepaid data plan is working, disable WiFi on the iPhone and look at the upper left carrier signal to see if Edge or 3G text appears, this will show you if the data plan is working. If data doesn’t appear to be working, restart your iPhone and things should work fine. This solution is described with screenshots by TheAppleBlog if you run into any confusion.

This exact process works the same on other carriers around the world, according to TheAppleBlog. The necessity of this varies from region to region though, as many countries have pay-as-you-go iPhone’s already available. The prepaid feature is not offered in the USA, thankfully it’s not that difficult to get around!

What about a prepaid iPhone 4?

Update: Here’s how to setup iPhone 4 as a pay-go phone, it’s pretty simple.

Update 2: Supposedly the CDMA iPhone 4 can be used on Cricket Wireless too, but it requires a jailbreak and some fees from Cricket.

The same process will work with the iPhone 4 as well, but since the iPhone 4 uses a micro sim card you would have to either trim down the prepaid sim which is a tedious process, or find another solution. If you plan on doing this, you’ll still need to buy iPhone 4 without contract which will cost quite a bit.

    does at&t even offer a prepaid data plan?

    • Nikki says:

      Yes they sure do! It’s 20.00 a month unlimited, and 60.00 a month unlimited for minutes/messaging, so 80.00 a month! =)

    • shelia says:

      Yes it does. You can go the walmart and it is back where the phones are. They are called Go phones.

      • Troy says:

        ok i did everything it said to get my iphone 3g on prepaid..and it said to put in a sim card that can be used on iphone.so i put in my prepaid card but when i try to make a call all it says it YOU ARE NOT ALLOWED TO MAKE THIS CALL..can anyone help me with this..please

        • banoscrew says:

          go to at&t and get a new go sim card. if u buy a prepaid phone the sim that comes with the phones are locked to that phone for 6months.. so just get a new sim from at&t and it’ll work fine.

        • Tom in Nanaimo says:

          1.after you insert the sim reboot.
          2.do you have a repaid sim card activeated with the said courier.must have paid money on the card to work.
          I regularly change out my sim data card with pay as you go card using both cards on a 3GS and have no problem.

  2. Ryan says:

    This is great news, however the data plan works out to $10/megabyte on prepaid. Maybe useful if you’re stuck in the middle of nowhere and want a google-map, but otherwise about the worst financial situation ever. Hard to believe there is no pre-paid data plan on a SIM available in the biggest, richest, tech-famous country in the world. Even harder to believe you can get a $20 unlimited plan on an iPad that is prepaid, but not on a phone….

    • Susan says:

      where can I get a $20 unlimited plan on the ipad? I cheched tonight and it was $25 for 2 gigs and they don’t have unlimited anymore for $30

  3. PeWiQu says:

    Does this also work with SIM cards bought on ebay etc for example this one:
    AT&T ATT Orange Sim Card 3G GoPhone?
    My wife will be travelling to the US and will be there for a week, phone is a priority although dataplan would be nice. Any further suggestions?

    Thanks in advance.

    • Moby says:

      Yes that should work but you should get Skype as a backup since you can use Skype over WiFi if all else fails. I did a jb and unlock on my iPhone before taking it to Europe and just bought a local sim, worked fine.

  4. PeWiQu says:

    Thanks!

    Hello,

    I’m wondering if anyone has had experience taking an existing, active iPhone account with AT&T from a regular “post paid” account to a prepaid one after their contract expires.

    There are ways to get an iPhone up and running using prepaid accounts (you can Google it to read more), and even get data going, but everything I’ve read has to do with taking an unused iPhone and putting a GoPhone sim in it. I have an iPhone that is out of contract but still in service, and want to take my existing phone number with me and do this.

    Anybody?

    • Peter says:

      Have you called AT&T to see if you can transfer your number over to a GoPhone account? I would start there.

      Peter

      • Scott says:

        I just transferred my iPhone to a goPhone account with AT&T and kept my AT&T phone number. It was hard to get them to do it. I had to go to two different stores until I found a cooperative store manager.

    • liz says:

      Yes, I did it. It was a HASSLE!!! I got my old number transferred to GoPhone — but I’ll tell you, it took HOURS on the phone, talking to AT&T, talking to GoPhone (yes, it’s separate numbers) and having people hang up, people say one thing and others say another, and especially having several people tell me it’s impossible. But it’s not! I have my original iPhone (and I do mean the first generation!) SIM card still in the original iPhone but use it as a prepaid phone with data turned off because it’s just too expensive. But it’s the same old number and works just great. You really have to put the time into it. AT&T stores told me no, many phone associates said no, and I finally had one guy say I could do it so I had to stick with his word (of course the notes on my account were never current or complete!)

    • France's says:

      Be careful with AT&T prepay unlimited they had hidden clause I had it they cut me off in the middle of my paid month refused to refund me had to write to corporate office and quoted the unlimited 50.00, 53.00 taxes, they released my number had to pay another 15.00 never got the rest of the month AT&T are robbers be careful they said I abused unlimited go figure

      • vuilnis says:

        The period is part of the written word. You can find it on your keyboard. Try it. You may like it. It will make reading your posts so much easier.

  6. Peter says:

    I would be careful with sims from other prepaid phones. The sim cards are locked to the prepaid phone for 6 months. I went to an AT&T store and just asked for a sim card… any AT&T sim card will work. It didn’t cost me anything. I activated the sim card online and had no problems.

    Peter

  7. mik33 says:

    Thanks Peter. I’ve checked, and you can transfer an existing out-of-contract iPhone number to a new GoPhone account.

    And, yes, I have a brand new not-yet-activated sim card, and I understand I can activate it pretty easily. But can I activate it and give it my existing (iPhone) phone number? I don’t have a GoPhone, incidentally (or any other phone).

    Like I say, it doesn’t sound that hard to set up a *new* prepaid account with a new phone nuber on an old iPhone; I just want to see if there’s a way to keep an existing phone number in doing so.

    • jeff says:

      Mik33,

      I think I am in the same situation. I have an iphone 3g at the end of its contract. I would like to keep the number on the iphone but switch to prepaid Go Phone minutes and worry about the data plan later.

      I really want to keep my iPhone with the existing number. Anyone know an workable way to do that?

      Thanks,

      Jeff

  8. alex says:

    I just bought the $20 unlimited data plan for an iphone-gophone.. At first it wouldnt work then I came accross this website and it seems to be working VERY well. THANK you a ton for figuring this out. I was going nuts. Im omw to AT&T to pick up another data plan thing for my girlfriend..

    Had one question though.

    Is it actually unlimited, or is it gonna run out? The people at AT&T informed me its unlimited, and you cant go OVER.

    thanks again!

    • alex says:

      Well I got it to work in my girlfriends iphone, but im having problems with mine. we both have a 3g, but hers had os4 on it and mine is on 3.1.. any suggestions?

      • Tom says:

        Make sure you activate the sim card before bringing it to the iPhone (do this on the goPhone to be sure or you can try online at AT&T, basically make sure it works already on AT&T by making a phone call or text). Then I would make sure you have the proper carrier file and settings.

        I did this successfully but I also have an unlocked/jailbroken phone, I am not sure if that makes a difference.

        • alex says:

          Ok so I thought it was because it was 3.1, so i updated to 4.0.2 and jailbroke it, do I still need to unlock it or something? I tried the APN thing but when I click create profile it says it cant create the profile. Its frustrating. any help would be appreciated or insight for that matter.

        • sergio says:

    • Tracy says:

      What website was it?

    • Awdrey says:

      Have you found out if it is in fact unlimited data? Will At and t charge me for using the data doing it the way this article describes?

  9. Susan says:

    I am looking at this to process credit cards. With pre paid is uning this to process credit cards at a remote site going to cost me a bunch of money? I heard we couldn’t get on even wifi without using the minites. Sure I can surf the web but at AT&T pre paided plan I would use up all my min fast. I’m looking at the ipad at $14.95 for 250 mb or $25 for 2gigs and a month to month plan

  10. paniol says:

    I have a 3G, with a GoPhone SIM (had to call AT&T to remove the SIM’s “binding” to the orig Nokia GoPhone that I bought 10 months ago). Luckily, my SIM is data enabled.

    I just purchase a data plan online on the GoPhone accounts website (have to login to AT&T — paygonline.com). I just get the $20 for 100MB, valid for a month. There is another plan that is $5 for 1MB, which does not make sense get.

  11. Ashley says:

    I am thinking of purchasing a friends iphone. He upgraded to a torch so I believe the iphone is off of his account. I would like to use it on att prepaid. My only question is what about activating it through itunes? Does this process bypass that? Thanks for your help!

  12. Greg says:

    Ashley, don’t activate it through itunes. Get an already activated AT&T prepaid sim and just stick it in the iphone. I hear you can buy actived sim cards on ebay, or you may be able to buy an activated sim at the AT&T store (just don’t tell them it’s for an iphone). Or if they don’t let you do that you could just buy a cheap AT&T phone (~$20) with a prepaid sim at the AT&T store …

    • wizkid says:

      Hey i have a 3G iphone 8G had bought thre phone using another friends name service the bill got to out of hand sharing the plan got stuck with the phone do not want to get rid of it but can i buy a pay as you go 3G wireless that way i can still use my wireless on the phone and pay per month and not have to connect to any unlocked wireless network around me?

  13. Amy says:

    My brother from Canada just gave me his iphone 4 (unlocked). I have a really old prepaid sim card, bought it when it is still called Cingular, it is a 64k smart chip, do I need to purchase a new 3g sim card in order to work with the iphone?

    The plan that I’m on right now is called “25 cent min w 10 cents m2m”, will it work with my new iphone.

    I guess I should switch to Simple Rate Plan, I couldn’t add data features to my current plan.

    Thanks.

  24. Brian says:

    Picked up a go phone and activated it a few days ago. Used it while my used iphone was in the mail. iphone came today. I put the go phone sim in but no dice? The iphone says no service. How should I proceed?

  25. Mario says:

    You don’t need to buy a gophone cell phone to get the sim card. Just go to an AT&T store and ask for a gophone sim card. It costs $25 and it comes with $25 of balance. I did this for my iphone 4 which I bought from apple store with no cotract for $600.

    • Jon says:

      Mario, you can buy a GoPhone at Dollar General for $10 on sale with the GoPhone SIM. But it won’t work in an iPhone! at least the first gen with OS 3.1.4 I did buy a regular AT&T SIM on eBay, (also from AT&T) and subscribed to the Senior 200 plan, so no contract, which I activated on my $10 GoPhone, then transferred it to my iPhone. Then I had to go through iTunes to activate it on the iPhone. So now I have a no contract, no activation fee iPhone for $29.99 a month plus $20 data plan that gives me 200 anytime minutes, 500 after hours minutes and unlimited “mobile to mobile” minutes…but NO rollover!

      I also bought a Motorola Razr V3 for H2O mobile from my local Fred’s Store for $30 and can transfer the SIM from the iPhone to that when I don’t want to take the more bulky iPhone out….it actually has much better sound quality, but no Apps. BUT contrary to many articles I read on-line, the GoPhone SIM will NOT work on the iPhone or for that matter the Razr. It only works on the original $10 Samsung.

      I have also read that since H20 runs on the AT&T network, if I activate it as a prepaid phone, it should also work on the iPhone as well as the Razr. By the way, the AT&T SIM costs $10 on-line from AT&T or on eBay, but the H2O SIM is only $1.00 on eBay (or $10 from H2O).

  26. Mario says:

    By the way, they sell the sim card already activated, so there is no need to activate it online or anything else.

    • Alina says:

      Hey Mario,
      just read that you bought an iPhone 4 without contract.
      So every iPhone will work with my usual AT&T simcard which i have to refill with unlimited texting every month and balance as soon as it’s gone? or what simcard do i need?

    • Steve says:

      Hi Mario, So u bought the $25 sim card from AT&T. Did they give you the Micro Sims or Normal Sims?

      Plz email me back to khh4less@gmail.com

      I want to use the data plan only from AT&T for my iphone 4

  27. JT says:

    put gophone sim in Iphone 3g, but it says “new sim detected connect to I tunes” Itunes says I need to call customer service to activate??

    Will ATT active this configuration if I call them?

  28. Brian says:

    Thanks. Apparently the go phone sim cards are locked to the phone for the first 60-90 days. I called customer service and they unlocked it. Now the phone works great.

    New question:
    When you enable data do you need a data package? If you will primarily use data in wifi spots but just want the ability to connect (just in case) while away from hot spots do you need to add a data package? In other words if I don’t log onto the internet while away from wifi will my phone access the internet and deplete my prepaid card?

  29. HG says:

    Travelling to USA. On my list to do, go by AT&T, buy $25 SIM, insert into phone. Then it should work. I already have a T-Mobile SIM, will that one work?

  30. SpammingSucks says:

    I’m amazed that this still works. With a little fiddling around I even managed to get the data plan to work. <3 my new gophone iphone

    • gouser says:

      as far as I see data plans for prepaid is extrememly expensive. where do you see 20/mo unlimited data? I see 20/mo for 100MB.

    • shanna says:

      hello can you give me some information on how you worked out your iphone with the prepaid plan?!

    • Steven says:

      Can you elaborate on what u had to do to get the data plan to work? I followed the instructions to a T, but only have phone, SMS service and only have Internet through WIFI. I even tried reinstalling with other US carriers. My phone was unlocked yrs ago so I don’t know if that makes a difference.. Thanks for any help u can offer!

  31. V says:

    Has anyone tried going into an AT&T store to purchase an ACTIVATED sim card for use on their iPhone?
    I purchased an unlocked iphone and a new unactivated gophone sim card online, but keep getting an error message when I try to activate it with my iphone on at&t’s website. Do i have to activate the card on another phone and then switch the card to my iphone? Could I just put the sim card in the phone one of my friend’s phones to activate it and then switch it to my phone without it impacting their service?

    This works 100% for the iPhone 4. FYI, I got an at&t SIM with my iPhone 4 even though I got it ‘off contract’ so I paid full price. Still locked to at&t but now I can us my PAGO 200Mb data plan and no need to sign a 2 year contract.

If I go purchase an activated gophone sim and put it into the iphone…is my only option for data the 200mb plan??!! I only use the web for maybe facebook every now and then and google searches..but I want to be able to download apps and use the web without it costing me an extra 500 a month!! Please help!

    • Barbary States says:

      @ kristin
      – Is your iPhone unlocked??? If it is, definitely get a tmobile sim card and use their UNLIMITED data service for $1.49/per day. Put $10 on your sim card and u can use the data service on EDGE for 6 days. Don’t worry about having to use it everyday! You have 90 days to use up those 6 days however u want.

    • Hope says:

      Hello, I have read all of the comments on here so far and they are very interesting. I just bought an used iPhone 3g from my cousin that was unlocked and I had put my GoPhone SIM card into it which I had for a year now. I do not want a contract so I had put my GoPhone SIM card into the iPhone 3g and worked!!! The only problem that I am having is that most of the time I do not have NO SERVICE and its frustrating. I have noticed that I do get service in certain areas. Are there any suggestions???

    • Hope says:

      Also, how do you upgrade to 4.1?

  49. Greg says:

    Kristin,

    The 200MB plan is NOT an option for a prepaid sim.

    You only have two data choices with prepaid:

    100MB for $20
    or
    1MB for $5

    That’s it.

    The only one that’s worthwhile is 100MB for $20, but even that’s fairly pricey. So you’ll want to download apps and watch video using WIFI, not 3G.

  50. David says:

    So, this is what I did.

    1) Bought an unwrapped new iphone 4 (clean esn) over the internet.
    2) Called ATT 800-331-0500, said “customer service” to the system, as the option is not provided.
    3) Requested the person assisting me to transfer my old pay as you go line to a new sim. I gave her the old sim number ICCID and the new micro sim’s ICCID. The micro sim was the one that came with the unwrapped phone.
    4) Provided my Iphone’s IMEI.
    5) ATT advised that this was an iphone and that they could do the transfer but I would not be able to use the internet. I agreed and line got transfered to new Micro Sim.
    6) Connected iphone to my itunes and immediately the phone showed a message that it was activated.
    7) I am now able to use my pay as you go in my new iphone 4.
    8) I jailbroke it using greepoison, and changed the APN through unlockit.con.nz to ATT and now I can use internet as well if I wish.

    • Hugh says:

      u said u can use the internet, but is that only with wifi, or can you use the 3g network, aka use the internet anywhere?

    • BK says:

      David, you write, “and now I can use internet as well if I wish” … my question is, after you change the APN though unlockit.co.nz, how much are you charged for the use of the internet. I would like to change the APN, but I don’t want 3G to drain my prepaid account. How much does it cost you to be online via 3G

    Could you buy apps with a prepaid sim?

    • Barbary States says:

      Yes, u can. Just make sure you have enough money on your att prepaid account. I use an unlocked iphone on tmobile and download apps all the time!

  55. VASHON says:

    DOES YOUR IPHONE HAVE TO BE JAIL BROKEN TO USE THIS ENTERNET???

  56. Barbary States says:

    Just unlock your iphone and use tmobile! You get unlimited data on EDGE only for $1.49/per day. Depending on how many bars show for your iphone, Apps should download pretty fast. If you have the AT&T pay as you go plan, make sure you have an alternative, which would be $10 tmobile pre paid sim. If only using the $10 tmobile sim card for data service only, it will give you 6 days of “UNLIMITED” internet usage on EDGE only!

  57. Raph says:

    Beware when using Internet with prepaid plN. My gf is using an iPhone 3GS 16g 4.2.1 jailbroken and we were able to activate usage of 3G. However, there has been lately several dollar taken fromher account for the use of internet. I told her to turn off edge and 3G And it was fine until she turned edge on and Internet was used and it sorta drained her balance. Keep in mind she uses Internet with wifi when she’s at home. Also, I talked to someone about using 3G on a prepaid plan go phone, and the lady told me that when you use Internet any day they automatically deduct like $15 from your account… Pretty crappy huh? Anyways, make surethat if u use internet, stick with wifi

    • Barbary States says:

      @ Raph, How much did she put in her account? Is she using AT&T or Tmobile? I would like to know how you guys were able to activate usage of 3g!

      • Raph says:

        Barbara
        She gets $60 withdrawn from her account. (39 for a few hundred minute, no longer available, and 19 for unlimited text message). shes using att. instructions to use 3g are above but here they are again.
        Be sure you are on a WiFi connection so you can access the web on your iPhone
        Using Safari on the newly setup prepaid iPhone, visit unlockit.co.nz and tap ‘Continue’
        On the next screen tap on ‘Custom APN’
        Select the carrier, for this example it’s going to be “US – AT&T” since using AT&T doesn’t require a jailbreak or unlock
        Tap on the “Create Profile” button to create and download the custom APN profile
        You will then see a screen saying you are about to install a new profile, click on ‘Install’ and then “Replace”
        A “Profile Installed” screen will appear next showing the new APN profile that has been installed
        The data plan should now work

    • Moon says:

      Hi Raph,

      did your gf sign up for the prepaid data plan that at&t has? i did purchase 100mb for $15 on my prepaid at&t sim card. i’m just wondering if she bought the data plan too, cause i’m afraid of getting drained too. I’ve been using the 3G network to browse the internet too =x

      • Raph says:

        Moon
        she did not purchase data package and I would not recommend it either because like I previously said she got charged randomly for internet usage. I follow the instructions right above to unlock the usage of 3g but I realized that’s not worth it either. The truth is, use your iphone with wifi and that’s it.

  58. Cole says:

    When I click create profile it changes the setting on my iPhone and sys install profile but the replace screen won’t pop up why is this ?? Please respond to my email I need help because the data plan is just too expensive

  59. Molly says:

    Ok, I’ve read all these awesome informative posts and would like to move forward but have one question… do you think this Go Phone prepaid sim card will work in my older iphone 16gb and an even more embarrassing ? lol, how do I get the sim card out?

    • Molly says:

      I need some techi help please! :) Thank you! not my forte, lol, very right brained,

      • liz says:

        Did you get it yet? My old iPhone works fine as a prepaid. I jailbroke it so I can use the Internet and everything. You need to use a paperclip — bend it so it’s straight and stick it in that itsy bitsy hole on the top and the sim card should come out. If I remember correctly.

    • Raph says:

      yes to ur first question, and google it to your second question.

  60. Raph says:

    Barbary
    Sha has Att and She had about $100 but over the nexo three months they took about $20 on top of her monthly billing.

  61. [...] would you need the IMEI number? There are plenty of reasons, ranging from theft protection to setting up an iPhone as a pay-go phone but here’s a few of the most [...]

  62. Linz says:

    I’ve read all the posts and am wondering if it’s possible to go back to using the iPhone under a contract after chanding it to prepaid and if all apps and saved info and such gets erased from the phone. Have people really found pay as you go more economical? I can’t decide if I want to take that step.

    • Raph says:

      it depends. i am in my fathers account and we have 5 lines and 3 iphones. the peeps who use an iphone pay ab out $60 or less every month (we grandfathered in the unlimited data plan :D). However, the company that I work for gives us a monthly 21% discount. with att current go phone accounts, they have the $2/day or $60 a month. I tried calling att to see if I can use an iphone and they said yes but “you may not be able to use internet”

  63. Sam says:

    I followed the steps – purchased a cheap Go Phone with active service. (Made one call to confirm service.) Swapped the Sim Card into an original IPhone. But the IPhone searchs then says “No Service”. Did I miss a step?

  64. Moon says:

    wow this is awesome, i get to browse the internet with my iphone 4 with my prepaid at&t pay as you go sim card. att charges $15/100mb and $25/500mb..

    • Raph says:

      keep in mind, 500 MB is not enough if u have jailbroken yourr phone or use the internet constantly

      • richard says:

        how come its not enough if its jailbroken? does it use more data when jailbroken?

        • Raph says:

          Well, here are tweaks when you jailbreak a phone that youcan install like weather app on the status bar, it refreshes every 5-10 minutes. Even though is not a huge consumption of data, it still uses some.

  65. Nic says:

    I was thinking of doing this and my mpother said it cant be done but … it can :P you can pay 10$ on the pay as you go and get 10,000 texts

  66. George says:

    THANK YOU THANK YOU THANK YOU!!

    :D

  67. Shane says:

    When I look up Pay as you go lans on ATT I see 2 smart phone options. Would these work with iphone 3GS? They are $2 a day unlimited talk and text or 10 Cents a minute talk plan and you can add text plan 200 texts for $4.99, 1000 texts for $9.99 or Unlimited texts for $19.99. Data plans can be added to both $15 for 100MB and $25 for 500MB. Would these work on the iphone 3GS? There are other plans, but they are not listed as smart phone.

    • Raph says:

      yes, it should work. you can even call att and tell them you bought an iphone off contract and you are thinking about getting a to go plan.

    • Jason says:

      I have this exact setup with a 3GS and it works great. Also, iv you renew your data plan on one of the last days of the 30 day period, you keep any unused data. So at this point I’ve got something like 240 MB of data I can use if I want to … which is more than plenty since I have wifi at home and work and there is free wifi in lots of the places I go.

      • Jen says:

        Jason,

        Does this still work? I’ve been wondering about rollover data. Are you talking like a day before the expiration? Two or three?

        Thanks!

  68. tiffany says:

    i just bought an iphone first generation on ebay and now i want to set it up with a pre paid account…do i need to have it jailbroken? jailbraking kinds of worries me i dont want to mess up my phone…im new to all of this please help…..

    • Potential says:

      No, no jailbreaking needed. Just activate the go phone using a normal phone, or the go phone it came with. Beware, once you activate it, the sim card will be locked to the go phone for six months, and you have to go to AT&T store to get a new sim that is under the same account ad the go phone to use the sim on the iphone

  69. Helpmeplease says:

    Can I use a Verizon iPhone 4 as a prepaid phone?
    Please help guys

  70. Jason says:

    I did these exact steps after getting fed up trying to figure out the whole jailbreaking thing and it worked perfectly. No jailbreaking nonsense required, and none of this “it’s locked to the phone you activated it with for six months”, either. The GoPhone was only active long enough to make sure that my number had ported properly to AT&T and then I swapped out the SIM and changed the APN. It’s been smooth sailing since. No complaints at all. No silly contract and I’m paying about $25/month with data, a messaging pack and minutes. I have yet to run out of data, talk time or texts because I’m not a heavy user of any of those things. If I want to be really cheap I could do just voice, turn off data and get my “bill” down to $8/month or so.

    This is how wireless should be. I just wish I could also (easily) pick the carrier by swapping out a SIM card. I know I can do that through jailbreaking but quite honestly I don’t have the time to pick up a new hobby.

  71. Kathryn says:

    Forgot to ask about paygo plans. I need unlimited talk,text. I have wifi at home(I would love to turn off home Internet as would be able to use on iPhone if better deal) I have no wifi at work or other places I go. I use pandora at work all day. What is the best plan if only need Internet at work and maybe for facebook, gps or somethng similar?

  72. Ray J. says:

    okay so ive read a few feed backs and im still a little bit conffuzed… can u make an iphone 4 prepaid?

  73. Rich says:

    Keep in mind that unused DATA kb’s carry over to the next month on the prepay ATT accounts.

  74. Kyle says:

    I was wondering if it was possible to take an iPhone and run it on a different brand, like net10? If you replace the iPhone sim card with the sim card from the net10 phone will it work with net 10?

  75. Rakeeta says:

    Hello, I have read all of the comments on here so far and they are very interesting. I just bought an used iPhone 3g from my cousin that was unlocked and I had put my GoPhone SIM card into it which I had for a year now. I do not want a contract so I had put my GoPhone SIM card into the iPhone 3g and worked!!! The only problem that I am having is that most of the time I do not have NO SERVICE and its frustrating. I have noticed that I do get service in certain areas. Are there any suggestions???

  76. shawn says:

    hey i just brought a iphon 3g and im trying to put it on at&t prepaid.. i figured id just buy a simple go phone from wallmart and swap out the sim after i activate it and i did so and the sim works in the go phone but when i put the sim in the iohone it says no service where do i go from here????

  77. angie says:

    if i was to switch a black berry into a prepaid would that work with a 20 message bundle and not charge me any more then that.

    plz reply,
    angie

  78. oldpinepoint says:

    This is what I did. I went to an AT&T wireless store and bought a pay as you go SIM without a phone. I popped it in my 3GS and i now have voice and text. i dont have any data and i havent tried the work around yet. Im afraid of getting nailed with charges. I think the trick is to get a prepaid SIM that isnt tied to a phone.

  79. MJ says:

    Has anyone tried this with Iphone 4 on ATT GO Sim recently? I have tried it today and it doesn’t seem to work any longer.

    Thanks

      MJ,
      I have been using it for 4 months without any problem.
      Now i am on 50$ unlimited plan.
      Only thing i m tryin to figure out is a way to use a data service with my iphone 4

      • Bader says:

        hi, MJ
        can you tell me how did you get the $50 unlimited plan? I have an iphone 4 with Pay as you go, but there is no unlimited plan show on the att website!

        -Be sure you are on a WiFi connection so you can access the web on your iPhone
        -Using Safari on the newly setup prepaid iPhone, visit unlockit.co.nz and tap ‘Continue’
        -On the next screen tap on ‘Custom APN’

        -You will then see a screen saying you are about to install a new profile, click on ‘Install’ and then “Replace”
        -A “Profile Installed” screen will appear next showing the new -APN profile that has been installed
        -The data plan should now work

    • Alex c says:

      works fine. Picked up a sim yesterday and after changing the profile it works fine on my iPhone4 (factory unlocked)

  80. Jason says:

    Alright, so let me clarify a little bit….I’ve read quite a bit about this…I bought a 3gs from a friend for $150.

    I then bought an orange 3G ATT SIM card. I called ATT, activated the card (when they asked for the IMEI of the phone, I told them I didn’t have a phone yet and was waiting on one). After the card was activated, they gave me a new number (kept my old cell phone active….I’ll be porting my number here shortly), and everything appears to be working.

    For now, I went with the 10 cent/min plan just to test everything out. Tomorrow I’ll put $10.00 on the account and see if I can make calls and texts. Oh! Almost forgot, I used an APN changer program to get data but for some reason, I’m only able to pick up EDGE (“E”) so far.

    I’ll be looking more into it as I go along….circumstantially, if I can’t get 3G data, I can’t justify $75 dollars a month for a plan with only 500MB. I’ll stick with VirginMobile ($55 unlimited EVERYTHING, talk, text, data 3G) and buy the Motorola Triumph for $300. If that’s the route I go, I’ll be selling this iPhone 3GS 16 GB w/ accessories here soon.

    Hope this helped a little bit. As for you iPhone 4 users….same process, except you gotta have your micro-SIM cut down.

    • prajesh says:

      hi Jason,
      You don’t need to cut the card. Just go to a att retailer and ask them for one. Tell them that you need a micro-sim. Its that easy.

    • Z says:

      My thoughts exactly. I mean, if its going to cost $75 a month prepaid and you have to go through all this trouble, why not just get a regular postpaid iPhone account for $85 a month? Not really enough savings to justify the hassle.

      I’m also looking at the Triumph on VM. $25 a month ($35 now I guess) is pretty sick…

  81. Aradh says:

    can you do this on other smartphones?

  82. Brian says:

    This was very easy to do. My 3G iPhone working perfectly on AT&T prepaid data.. Thanks a bunch

  83. Hakmid says:

    Does this still work? I used us.att for my carrier. When i try to connect to internet it tells me that i cannot connect to server.

  84. ryan says:

    When i press install the replace screen never comes up. and the internet never works. help… I took it into a store and had them give me a chip. did they do something to know I am using an iphone?

  85. shanna says:

    so the only way you can use the internet is if you get a date plan?! or will you be able to use the internet without the date plan?!?!?!

  86. Abstrak says:

    I get unlimited pic/video/text messages, unlimited minutes, 500mbs of data, and 10 hours of international calling even to mobile numbers. All without a contract and no need to jailbreak or unlock your iPhone. So nana nana boo boo I’m better than you:) h2o

  87. Abstrak says:

    All this for $50

  88. Gretchen says:

    Here’s my dilemma: I have a certain computer technician ‘stalker’ that has SOMEHOW managed to access and delete my voicemails. My Iphone 3GS does weird things sometimes like shuts off, or gets ‘frozen’. I have a contract w AT&T. I pay on average $120 a month. I use my phone for EVERYTHING! To paying bills online, texting a billion times a day and talking to family out of state. To discourage the stalker, I’ve changed my number (so far) a total of 3 times. An hour or so after I have paid $36 to have it changed, the stalker calls. I’m sick of the ‘blocked’ calls. And I’m sick of worrying about my privacy. Sooo…I thought if I get a prepaid with my iPhone, my phone will no longer be able to be accessed by unwanted people. I’ve read alot of helpful posts, but alas…I’m still confused. Anything is better than $120 a month! I use my iPhone religiously, so I can’t part with my 3G.
    Any suggestions or advice would very much be appreciated. : )

  89. Ebony says:

    Will this process still work with the new prepaid plans, or will I still have to buy a data package?

  90. Jordan says:

    So, Theoretically. If I walk into the AT&T store, and ask to buy a go phone sim card, they’ll sell it to me without getting suspicious, and it will be unlocked and have minutes on it?
    Then I put that sim card in my unlocked iPhone?
    Right? D: help please, I dun wanna data plan just the regular plan.

  91. Jordan says:

    The unlimited Data plan on the 3g still doesn’t work / ATT PREPAID $50 plan. Nope.

  93. Bethany says:

    It worked! Tonight my husband and I went into AT&T and purchased a $25 pay as you goPhone SIM card. They gave us a new phone number and didn’t ask about what kind of goPhone we have. As of right now we aren’t interested in data… just phone capabilities. We came home and put it in my old iPhone 3G (which has just been sitting around the house) and it worked perfectly! No jailbreaking required!

    • Bill Condie says:

      You wrote: Tonight my husband and I went into AT&T and purchased a $25 pay as you goPhone SIM card.

      So I didn’t even have to buy a phone? Was the phone number built into the SIM or did they set that up for you?

      I’m about to fix up a friend’s old iPhone

  94. Jordan says:

    Okay, just got the phone, haven’t paid for service yet. Can I use iron like wifi and stuff until I do?

  95. Bill Condie says:

    I got it up and running on a 3gs by following the article, for which I thank you!

    I then added a minimum prepaid data plan. Great to have Maps working again.

    Having Line2 for WiFi and the GoPhone sim for out of the area is working wonderfully. Calls to Line2 automatically forward to the GoPhone number.

    Billing is a problem. I added $25 before I removed the sim from the phone. When I put it into the iPhone I had to add funds. Not wanting make waves I just paid.

    Is ATT gonna cut us offf when they realize what we are doing?

  102. Sardou says:

    and if so what are the steps to activate it ?

    • Dean says:

      Yes it will work. Get a regular sized ATT GoPhone sim card. You can buy one on eBay for just a few dollars.

      1. Go to http://www.wireless.att.com/activations and select Pay As You Go as your plan. Hit Next.
      2. Enter the 16 digit code from the sim card, starts with 8901. Hit Next.
      3. Enter your zip code (so it can assign a local phone number), and in the IMEI box, enter all 0′s. Hit Next.
      4. Enter your email. Hit Next.
      5. Choose your plan. $50, $2 per day, or 10c per minute. Hit Enter.
      6. Review your information. Click Submit.
      7. After it sets up your new account it will give you a phone number and passcode. Put the sim card in your iPhone. Turn on the iPhone, and enter the passcode. Your iPhone can now make phone calls.

      If you only want to use the iPhone for calls and for wireless internet via WIFI, you are done. If you want to use data/internet/etc. from ATT, you still MUST make some changes…

      8. Sign into your ATT account, and sign up for a data plan, under Buy Feature Packages. They start at $5 per month.
      9. After signing up for a data plan, using a WiFi connection on the iPhone, open Safari and go to this url: http://www.unlockit.co.nz/unlockit/
      10. The website will ask for what carrier APN profile to use. Select ATT. It will complete the changes to your phone and now you can use ATT wireless data in addition to WiFi. This is not a jailbreak, it just changes the APN settings of your phone so it recognizes ATT’s wireless service for data. This can be set back to factory settings anytime by doing a reset.

      Enjoy.

      • dasemae says:

        Dean, you said go buy a data plan for the iphone and then do the APN changer….. do you have to have the data plan first for the APN changer to work cause just doing the APN changer with the 50.00 unlimited does not work for me.

I’m goin to take the sim out of the 3GS and put it in the new iPhone. I have a brand new gophone 3G sim and a pay as you go card. Could I activate the sim and put it in the 3Gs and will it work? My concern is because the 3GS was bought in may and I dont know if the prepaid 3G pay as you go sim will work in the phone. PLEASE HELP ASAP

  109. Lena says:

    I have an iPhone 3GS running iOS 5.0 and I used this method. It worked for a week or two, but then it stopped working. Does anyone have any suggestions for how I can fix my data WITHOUT jailbreaking? I can make/receive calls and text, but data doesn’t work at all.

  110. Dave says:

    It pays to read the most recent comments!?!

    Well, I saw the $50 plan with unlimited data and thought this would be a good deal, so I bought an iPhone 3GS from a friend who just got a new 4S.

    The local AT&T store gave me a new SIM card for free. He asked to see my phone, and I showed him my T-Mobile pre-paid (non-smart) phone. He said he wasn’t sure it would work, but I assured him it would. He wanted to activate it immediately, but I told him I needed to use up all of the minutes on my old plan first. So he just scanned the card into the computer and handed it to me.

    I thought I could do everything on-line with the AT&T website, but it wasn’t quite so simple because I wanted to port my phone number. I had to activate the card on-line and then call a number. The one they had on the first activation page wasn’t correct, but they eventually got me routed to the Porting Dep’t at 1-888-898-7685.

    Amanda was very helpful and even called T-Mobile to get my account number — it turns out that T-Mobile account numbers for pre-paid phones are the same as the phone number. But they transferred the number from T-Mobile to AT&T right there on the call — even though the AT&T system showed that it was going to be delayed. The T-Mobile person authorized the transfer so that it would go through immediately.

    I didn’t add money to the account after I activated it but before I called to transfer my phone number, so we had to do that while I was on the call. I’d recommend that you add some money right after you activate it — even though it still has the new number and not your old number.

    We tested my old phone, and it worked. I hung up and immediately took the SIM card out of my old phone and put it into the iPhone. I got the bars and AT&T and was able to call my landline.

    I went to the website listed above and walked through the steps, using ATT as the plan. I then turned off wifi and turned on cellular data. That showed the E (I guess for EDGE). I turned on 3G and that showed the 3G.

    But, Safari said it couldn’t find the server!?! So I started reading through the more recent comments above and saw that AT&T has wised up and blocks data traffic from iPhones unless you add the Data Plan Feature to your account. Drat!?!!! So I added the $15/100MB option to my $50 plan, meaning I’ll now pay $65/mo. instead of just the $50 I’d hoped for. C’est la vie.

    BTW, I tried to activate the SIM card with the IMEA number from the iPhone, and it kept timing out. It activated fine — albeit just as slowly — when I used the IMEA number from my old (non-smart) phone.

    I hope this helps and I hope you’re reading this before you get your hopes set on a $50/mo unlimited data plan!?! :-)

    • Brittany says:

      Wow, I should have read your post first. So if I just add another data plan on top of the $50 unlimited plan this will work??

  111. Lena says:

    Dave, I added a data plan on mine and it worked for awhile but then it stopped working even though I didn’t use it all up. Not sure why it’s working for you and not for me, but I was assuming AT&T figured out what I was doing and blocked it on my account or something.

    I have been using the prepaid option on the 3gs for about 9 months now. If I update my phone to ios 5 will that mess anything up?

  113. Jacob says:

    SO THE 50 Dollars unlimited no longer works?

  114. Nookleer says:

    Ah damn… I wish I had read this before ordering the plan..

    Lol.. Ok, so the APN switch works for the pre-paid plans just fine, you’ll just burn through the data much faster with an iPhone than with almost any other phone.

    However, the $50 unlimited plan does NOT work..

    “Why?” you ask?

    Apparently AT&T has developed a new app of some sort that allows them to request, from the sim, the model of the phone you are using. Once it detects iPhone on the unlimited plan, you’re done.

    This was told to me by a rep when I called.

    Wish I checked here before i paid the $50 :)

  115. Chad A. Bryant says:

    I was able to get an iPhone 2G onto the $2-a-day GoPhone plan (I already have a main phone, and I only need this phone on the weekends). I purchased a naked SIM from my local AT&T store, and they activated it and took $15 from me to put towards the balance. This is *much* easier than buying a SIM on eBay/Amazon, or wasting time with a cheap GoPhone package that results in a locked SIM followed by a trip to an AT&T store.

    Talk & text work just fine. I don’t really need data (wi-fi is excellent), so I haven’t bothered to enable it.

    • JebNY says:

      I agree walking into ATT would be easier, but I’m 20 miles away from the nearest ATT store, and the mail is delivered to my door. Never had a cell phone before so waiting 2 days for the SIM to show was not a problem. I decided to go with H2O for two reasons, cheaper for people that don’t use a phone much and it looked like ATT really didn’t want people to use Go cards on an iPhone and you basically had to lie to them on what phone you were going to use (hear say only). I didn’t want a data plan either and would not try to get around rules that ATT seems paranoid about. GoPhone(lie if I must) was my first choice till I stumbled across H20.

      Jim…

  116. Aaron says:

    Worked like a charm. Sadly being in an area with limited 3g coverage, it takes forever and a day for anything to load. Would be good in a better 3g area

  117. Regina says:

    Hi! I have an iphone4 and iphone 3gs and I’ve recently decided to get out of the contract because it’s way too expensive for me. Anyways, I want to make my both iPhones as a go phones. I already have the go phone micro sim card activated and the other one for the 3GS as well. For some reason it keeps telling me that it has no service. I took the sim cards from the go phones I just bought. I’m not really sure what to do its kind of frustrating! Any advice/help would
    be greatly appreciated. Thanks!

    • JebNY says:

      I have heard that if you activate a GoPhone that the Sim is locked to the phone for some length of time.

      Jim…

      • JTW says:

        It is only locked into the Go Phone if you put the newly activated sim card directly in the Go Phone. Then the card is locked into the Go Phone.
        If this happens, go to AT&T store and tell rep that you need a new card and they will take your information and give you a new card (if you need to make up a story about losing your card, then do it). Then take the new card and place it into your iPhone.

  118. MD says:

    I have two iphones (a 3G and a 4). The 3 is inactive…but it had the same phone number as the iphone 4.

    How do I change the phone number on the 3G? Or, does the sim card have a unique phone number attached to it?

    I’m thinking about purchasing a GoPhone, then telling AT&T my sim card isn’t working and getting a replacement that is unlocked. Will that SIM card be tied to the phone number of the GoPhone, or will it pick up the phone number assigned to the iPhone 3g?

  119. Mark says:

    If i do not want data on a pre-paid Rogers pay as you go plan and i am not connected to wifi will it allow me to use the internet and just charge me for the data i use? I dont want to pay for data and am content to only use the internet while connected to WiFi but am concerned that if i don’t realize im not connected to WiFi and am browsing that it will cost me!

  120. Joe says:

    I have iPhone 3GS and my contract with AT&T is over. I just switched to Gophone service today without a data service.
    I kept the old SIM card and phone number but was told by the AT&T store manager that my old SIM will no longer work with IPhone (because Gophone is not supported on iPhone) and that I transfer the old SIM to a new phone.

    Well I can see a message on the iPhone that I no longer have cellular data; which is fine. However my voice service is still working on the iPhone; I can still originate and terminate voice calls using the old SIM and phone number with Gophone service on my iPhone, but my old voicemail greeting is no longer working.

    So I’m confused! Do I keep using Gophone plan with my old SIM and number on the iPhone or should I get a new phone as recommended by the AT&T store manager. Is my new Gophone voice service going to stop working after I reboot my iPhone?

    • Koji says:

      @ Joe:

      If it is working fine, you do not need do anything.
      Your iphone is locked to AT&T, so as long as you use an AT&T Sim card, you’ll be fine. Gophone Sim is AT&T, so there’s no need to do anything.

      The AT&T store manager is just repeating what he has been told by AT&T corporate, because AT&T will not make much money if everyone knew you can use the iphone with gophone sims.

      To use data, add a data package to the SIM card AND configure “custom APN” as detailed in the article above. You can add the data package here: https://www.paygonline.com/websc/index.jsp

  121. Awdrey says:

    Can anyone help me, I got the gophone sim to work in my iphone, but can not get the data thing to work. Please help!

  122. cody says:

    So if I buy my friends iPhone 3G I can use a cheap phone’s sim card, buy the $50 unlimited talk,text, and web card, it will be able to browse the web?

    • JTW says:

      The $50.00 Unlimited Plan will not give you unlimited Data on the iPhone. AT&T has disabled this on the iPhone. You will need to buy the additional data from AT&T.

  123. Awdrey says:

    So I’m still wondering if my iphone 3gs will work with AT & T’s $50 unlimited talk, text. and data plan. Is it blocked where you can not use the data? If it is blocked, will they let you add a data plan to an already unlimited plan????? Please help thanks!

    • Dude says:

      I read everything on here and I still wonder the same thing, does anybody have any recent experiences with this?

      Does it still work and do I have to add a data plan or does the $50 unlimited data apply?

      Trying to do this on an (ex-contract) AT&T iPhone 3G.

      Thank you for any help!

      • Dean says:

        Yes, but you have to add a data plan. I get the unlimited plan for $50 and 100 mb data plan for $15 more and works like a charm on my 3gs

        • JTW says:

          I’m going to use the $25 plan (250 minutes of talk and unlimited messaging) and maybe buy the data later. With all the free WiFi hot spots, I don’t see the need to buy the additional data plan.

  124. anonymous says:

    I have a jailboken iPhone 3G in my house. I have had the same old phone for a while, and was wondering if I could put the sim card from that into the iPhone without AT&T knOwing or getting charged extra. I do not need or want 3G.

  125. Tida says:

    Can I use minute card on my iphone 3G

  126. ashley says:

    YOu can not get the sim card out of a iphone.
    So obviously this DOES NOT WORK!

    • Gman says:

      um ur wrong because u can, on the top of ur phone there is alil hole stick a tooth pick in there and the card comes out

    • dasemae says:

      um actually you can you need to take a small pin and stick it in the top of your iphone to make the card holder pop out!!

  127. Steve says:

    I have an iphone 3gs. I purchased what I thought was a refurbed Samsung gophone however when it arrived it was new. The sim is locked to this phone for 6 months. I will get another sim card from an AT&T store.

    Can anyone provide the exact details on activating the new sim without using the IMEI number from the go phone. I have also set up a go phone account.

    Thanks

    • JTW says:

      The IMEI number is not important. Just use either the IMEI number from the Go Phone or just use zeros at set up/activation. The real key is not to put the Sim Card in the Go Phone, once it is in the Go Phone it will be linked/locked into the Go Phone. After activating the Sim Card, put the card in the iPhone.

  128. Brittany says:

    Ok I have a used iPhone 3g.. I have a prepaid SIM in it and have the Unlimited Talk, Text, & Data for $50/month. It works as far as talking and texting goes, and I can use Safari as long as I use WiFi. I have followed these instructions to a T, restarted the phone and I see the 3G symbol at the top but when I go to Safari I get this message: “Safari cannot open the page because it could not connect to the server.” SOMEONE PLEASE HELP!!

    • JTW says:

      The Unlimited Data plan on the Go Phone doesn’t work on the iPhone. You will need to add the Data Plan from AT&T Activation page.

  129. Kim says:

    I am having the same problem as Brittany. I read somewhere that the phone is in recovery mode, but not exactly sure what to do about it. Help for the common everyday person would be a HUGE plus.

    Thanks!

    • JTW says:

      The Unlimited Data plan on the Go Phone doesn’t work on the iPhone. You will need to add the Data Plan from AT&T Activation page.

  130. Nick says:

    Thanks works like a charm!!!!

  131. Jon says:

    Hi I have a Iphone 3gs Im trying to use for a go phone. Bought a samsung att go flip phone realy cheap, but havent put minutes on it in a while, do I need to add minutes to it before the “no service” on my iphone will go away? im lost, really need some help?

    • JTW says:

      Most likely the phone number on the old Sim Card is no longer valid due to non-use. You will most likely have to get a brand new Sim Card with a new number as the old one has been deactivated (and old number recycled by AT&T).

  132. Jon says:

    I just restarted the phone, and now its saying “insert valid sim with no pin lock to activate iphone” does this mean i need to get a unlocked sim card from att?

    • JTW says:

      New card is probably needed. Just go to AT&T and tell them you need a new Go Phone Sim Card because you didn’t use the old one in a while. Tell them you don’t need a new phone just a new card to use in old phone. They probably will give you a new one at no charge.

  133. Jon says:

    Ok, I checked the phone today, and it apparrently has minutes left on it, i was able to send text and use the phone, so im assuming just getting a new sim card should work in my iphone? So that’s all I need to get it then and it should work?

  134. Ernie Pantuso says:

    I was all set to do this until I realized that the $50 unlimited talk, text and web was really just talk and text. If I have to add a data plan, it’s not such a great deal any more.

    Isn’t there some APN (from the unlockit.co.nz site) I can use so that AT&T won’t see my phone as an iPhone???

    Other questions:
    Does MMS work?
    Does visual voicemail work?

    Thanks in advance for the help/answers.

  135. Actually none of this matters, now. Net10 is now offering a program where you can use your iPhone on their service for $50/month – unlimited talk, text and data! No extra data plan required AND it doesn’t use AT&T towers exclusively – it uses T-Mobile and other GSM towers as necessary. All you have to do to get started is order a $15 SIM card from them.

    FINALLY! This is the plan I’ve been waiting for!

  136. Marco Soliz says:

    @Ernie Pantuso
    That`s AWESOME!!! I`m going for it! Thanx for the heads up!

  137. AngieK says:

    I want to buy an iphone 4. Will it work as a go phone through Boost Mobile and how do I do that…get a new sim from Boost? OR, would I do better going through Net10 and do I need to buy a Net10 phone for the new sim card and activate it in the iphone? Thanks in advace for the help…I am NOT very educated in this subject, but, I’m trying to learn :))

  138. aja says:

    I followed the steps above and my iphone is working with talk/text, but I can’t get the internet to work after I downloaded the apn and restarted the phone. I had a contract iphone with at&t and now have a pre-paid micro sim. Are there any suggestions, the main reason I wanted the phone on prepaid was to use the internet. I had put a $15 balance on the card but used the option of not having a monthly plan but literally pay-as-you-go.

  139. javaughn says:

    i bought a iphone 3gs and put a sim card from a at&t store and when i turned on the iphone it says no service the sim card is activated and has 20 $ on the card

  140. Jon says:

    OK. So I understand before I do this. I currently have GOPHONE. If i purchase a used I phone I can use my sim card in it. I have gophone 50.00 a month unlimited plan on voice message and data. Will the data work on the I PHONE this way ?

  141. Sara says:

    My question is, I have a iphone 3g and a pre paid plan but I can not recieve any pictures that come from other phones only iphones! Is there anyway to fix it so I still recieve pictures?

  142. Kendy says:

    I have a question we have been stationed overseas for three years and bought our 3GS iphones here. Can I bring this phoen back to the US and put a prepaid sim card in it or do I need to unlock it since it is an international phone?

  143. nick says:

    iphone on gophone prepaid

    will work. must use minute/text plan plus a seperate data plan (all prepaid). iphone will not work with the data that is on a unlimited plan for att prepaid. 25$ 250min/unlimited text plus 25$ 500mb data plan equals 50$ bucks, not bad if you never talk on the phone.

  144. Mak says:

    I want to buy an unlocked iphone 3gs. does anybody have any recent experiences with this? I have an prepaid sim card, do i need get new one?

    • Alicia says:

      Are you still interested I have an iPhone 3gs for sell on ebay, username ajam6888; only problem I’ve encountered is being unable to send or receive picture messages…AT&T said it’s b/c I am on a prepaid plan with the iPhone.

  145. Jake says:

    I just recently setup my iphone 3gs with ATT prepaid.
    I bought a $15 go phone and activated the account in the cheap phone. I then took the sim card out put it in my iphone and it did not work. Called ATT support and asked to have the sim unlocked. When I called them I put the sim back in the cheap phone and it was unlocked while I was on the phone with ATT. I then put it back in the iphone and voila!

  146. Joe says:

    I went to an ATT store and bought a prepaid SIM card. There is no charge for the SIM card itself but there is a minimum of $25 which must be used up in 90 days. I got a new phone number to go with it. Plug it into my old iPhone 3 (still locked to ATT) and it just works!!!

    The 3G data is active but I did not test it as I have no idea how the charge will reflect. Instead I turn off 3G and Celluar Data.

  147. Channy says:

    I have a 3gs and it has the 5.1 iso and I have tried to get the data the way this describes and I can get it downloaded and create a pofile but it does not give me the option to replace and it will not work without wifi. Any suggestions????

  148. Greg says:

    IMPORTANT UPDATE: AT&T now requires a $25/month plan to purchase data packages! With a $5/month data package, you’ll be spending a minimum of $30/month.

    For a cheaper prepaid alternative consider Airvoice wireless’s $10 plan (calls 4 cents/minute, texts 2 cents, data is $.33/MB). Or if your phone is unlocked take a look at Tru (calls $.17/minute, data $.17/MB) which runs on T-Mobile’s network.

  149. dean says:

    can i use the $50/mo plan with my prepaid sim in my iphone and have internet thanks

  150. Braad says:

    Hi, everything I’ve done has worked except I have a prepaid android, I took the sim out and put it in the iPhone 3GS and it says I have no service!! I don’t know what to do. I’ve had the sim in the other phone since Christmas so it seems like it shouldn’t be locked to it anymore! Please please someone shed a little light. Thanks.

  151. Illinoisjoe says:

    help! This worked for me for months but last weekend I suddenly started constantly getting a “no service” message on my iPhone 3gs. Bummer! I think ATT finally figured out I was using an iPhone and booted me. Any advice? any work arounds? any one else have this issue recently? Att sux.

  152. marnie says:
